INTKODUCTION 

TO THE 

ASTRONOMICAL OBSERVATIONS OF 
1868. 



During the year 1858 the Personal Establishment of the Obser- 
vatory consisted of the Director, Manuel Johnson, Esq., M. A. ; and of 
three assistants, Mr. Norman Fogson (now Astronomer at Madras], 
Mr. Adolphus Quirling, and Mr. (George Green. Throughout the year, 
with very few exceptions, Mr. Pogson made the observations with the 
Transit Instrument, and Mr. Quirling those with the Meridian Circle, 
while Mr. Green had the chief charge, under the inmiediate superin- 
tendence of the Director, of the Photographic Meteorological Obser- 
vations. ' A lad named William Harris was also employed to assist in 
the Meteorological Seductions and other work. 

No change whatever was made in the Instruments or in their 
mode of use. They consisted chiefly of the Heliometer (only in 
occasional use during the year) and of the Transit Instrument and 
Meridian Circle used in preceding years. With the Heliometer a 
few observations of double stars and of Tuttle's Comet were made 
by Mr. Quirling, which will be printed in a following volume. A 
Chronographic apparatus, similar to that at Greenwich, but smaller, 
was mounted on the pier of the Transit Instrument in the early part 
of the year, and a few observations were made with it by galvanic 
contact, but, on account of diflBculty in the management of the clock, 
the use of it was soon discontinued. 

Other Instruments for occasional use were, 1st, a telescope of 
10 feet focal length, and 7 inches aperture, mounted equatorially on 
the south front of the Observatory, and provided with a journeyman 
clock, striking at the termination of each minute; and a 42 inch achro- 
matic telescope, with triple object glass of 3I inches. Observations 
and discoveries made with the lo foot telescope in preceding years by

ii Introduction to the Astronomical Observations 

Mr.Pogson have occasionally appeared in the AstronomucAe Nachrichten 
and the Monthly Notices of the Royal Astronomical Society. 

The ancient instruments out of use consist of two brass 8 foot 
Quadrants by Bird, and a i a foot zenith sector, in connexion with which 
may be mentioned an old barometer by Bird, and an old but serviceable 
astronomical clock (still kept going) by Hawting of Oxford. There is 
also a lo foot Newtonian telescope by Sir W. Herschel. 

In addition to the clock previously mentioned, there are three 
others^ used respectively with the Heliometer, the Transit Instrument, 
and the Meridian Circle, the two first by Dent, with mercurial com- 
pensation pendulums, and the latter by Shelton, with gridiron pendu- 
lum. All these are excellent instruments. There is also a clock with 
wooden pendulum, which stands in the hall, and serves to give time 
for the regulation of ordinary business. 

A pocket Chronometer by Hardy is used for comparison of clocks 
and for occasional observations. 

The Barometer used with the Heliometer is by Jones, and has a 
bag and adjustible float for the adjustment of the level of the cistern ; 
the other is by Newman, and has a fiducial point, which in use is 
brought into contact with the surface of the mercury. 

Section I. — Observations with the Transit Instrument, Pages i to 69. 

The telescope of the Transit Instrument has an object-glass of 
4 inches clear aperture, with a focal length of 8 feet. The magnifying 
power of the eye piece generally used is about 100. The Instrument 
is fully described in the 4th Volume of the Radcliffe Observations. 

The observations were made by Mr. Pogson. 

The first column of the printed observations contains the reference- 
numbers to the foot-notes on each page. 

The second column contains the date of observation, commencing 
with the Sun's transit. 

The third column contains the designations of the stars or other 
objects observed. For stars in the Nautical Almanac, the names there 
given are preferred to all others. For stars contained in Baily's 
Flamsteed, the Greek or Italic letter of Bayer there adopted is used, 
or in defect of that, Flamsteed's number, with the name of the con- 
stellation. For other stars, the British Association Catalogue is pre- 
ferred to all other catalogues, and then, in order of preference, the 
numbers in the Catalogues of Groombridge, the Radclifle Catalogue, 
Piazzi, BessePs Bradley, Baily's Flamsteed, Carrington's Red Hill 
Catalogue, Weisse's Bessel, Lalande and Lacaille (as published by the

British Association)^ Oeltzen's Argelander, and Riimker, are used. 
For variable stars the letters in ordinary use are employed^ these 
letters being included in brackets to prevent confusion. 

Stars which do not occiu*, or which have not been identified in 
any of the Catalogues mentioned above^ are designated by their 
approximate N.P.D., given in general to the nearest minute. 

lUinQ fourth column shews the number of wires over which a star 
has been observed when the observation was incomplete. 

The wires are the same as those which have been in use since the 
year 1843, excepting that, for observing by galvanic contact, two 
additional ones were inserted in the year 1858, half way between the 
centre wire and each of the adjacent wires. They originally consisted 
of seven fixed vertical, 14' apart, and two horizontal wires, 30'' apart; 
and of two wires moveable by separate micrometers for observation of 
the error of collimation. 

Thefftk column gives the time of transit over the mean of the 
five central wires at small intervals used for the observations by 
galvanic contact. All the observations throughout the year, though 
in general made over the seven wires at wide intervals, have been 
reduced to the mean of these five, because it was intended at the time 
that the Chronographic apparatus should be constantly used. Calling 
the wires in the order in which stars pass them, when the illuminating 
lamp is east, a, i, c, d, &c., the distance of each wire in time frgm the 
mean of the five is, for an equatorial star,

These results were deduced from eleven observations of Circum- 
polar Stars in January, 1858, and have been used throughout the year 
for the reduction of imperfect transits. 

For stars within 10^ of the pole there has been used the accurate 
formula — 
Sine distance of star from mean of five wires = Sine Equatorial Interval x Sec. Decl". 

For other stars the approximate formula has been used. 

Distance in time for star = Equatorial Interval x Sec. Decl".

iv Introduction to the Astronomical Observations 

The Sun was not observed during the year 1858. For the reduc- 
tion of imperfect transits of the Moon the usual formula has been used^ 
namely 

^ X- X * • 3600 + 1 SinGeoc. Z.D. „ ^ , 

Correotioii to mean of wires = -=^— ? x -?- — ; „ ^ x Sec, Ded". 

3600 Sin App. Z.I>. 

The sixth column contains the sum of the corrections to be applied 
to the transit over the mean of wires on account of the errors of col- 
limation^ levels and azimuth. 

The Error of Collimation of the centre wire is determined by the 
observation with one of the micrometers^ in reversed positions of the 
Transit Instrument^ of two terrestrial marks^ seen through lenses fixed 
in stone slabs inserted into the walls^ at the north and south shutter 
openings of the Transit Boom. The north mark is about 180 feet 
distant from the Observatory^ the south one about 300 feet. 

If e and w be the sums of the readings of the micrometer ex- 
pressed in arc, corresponding to lamp east and lamp west, when the 
micrometer wire bisects the marks, and k the reading when it is in 

coincidence with the centre wire, i is the error of collimation 

4 
of the centre wire. This requires correcting by — o"'i9 for diurnal 

aberration, and by +o"*i8 for reduction to the mean of five wires, 

according as the lamp or perforated pivot is east or west. It should be 

observed that, of the two micrometers attached to the eye-piece, that 

one is used which is on the same side of the telescope as the perforated 

pivot or the illuminating lamp, and that its readings increase as the 

wires move towards the head of the micrometer. 

If the error of collimation thus corrected and expressed in are be 

<? I 
c, then the correction to transits in seconds of time will be — 



15 Sin A 
for a star whose N.P.D. is A. 

The Error of Level is determined by means of a hanging level, 
Aimished with a divided ivory scale, the assumed value of one division 
being i"-5. 

The axis of the Transit Instrument is generally levelled every 
evening when there are observations, the level being reversed four 
times. The readings of the scale at both ends of the bubble being 
taken, and those of the west end being considered positive, their alge- 
braical sum divided by twice the niunber of reversions, if the diameters 
of the pivots be equal, will be the inclination of the line joining the 
centres of two pivots. 

No sensible difference has been detected in the size of the pivots, 
and their figures, as far as the level is a test, appear to be faultless.

The correctioii in time to an observed transit, corresponding to a 

level error i, is ^, —, where A is the North Polar 

15 SmA ' 

Distance of the object, the error being considered positive when the 

western pivot is too high. 

The Azimuthal Error of the Transit Instrument was determined 
by pairs of stars within 6° of the pole, observed at opposite culmina- 
tions. The adopted Mean Right Ascensions of these stars will be found 
in the Catalogue given at pages 70 to 76. 

If a and o' -f 1 2** be the Right Ascensions of two stars used thus 
for determining azimuthal errors, and d = a— a ; and if t and if 
represent the times of transit of the stars, the latter corrected for 
dock-rate if necessary, and t—f — d; then, denoting by n and n* the 

factors of azimuthal errors, that is, the values of ^— -^r — i — - 

' ' I ^ Sm A 

d—d' 

for the stars, the azimuthal error will be equal to -, - 

n — n 

If the azimuthal error thus found be called ??£, considered positive 

when the western pivot is too far south, then its effect on transits of 

stars will be -^. — -, and a table of the values of the 

15 Sm A ' 

error throughout the year, together with those of coUimation and 

level, will be found at pages 77 to 81. 

The 9eventh column contains the clock-errors actually applied to 
each transit, as deduced by combining the separate clock errors 
actually observed and recorded in the eighth column. 

The assumed Right Ascensions of the stars used for determining 
clock errors have been, as in former years, derived from the Radcliffe 
Observations of preceding years, all stars whose N.P.D. are greater than 
40"* and larger than the 8th magnitude, which had been observed at 
least twice, being considered eligible for the purpose. The Right 
Ascensions are therefore referred fundamentally to the same equinox 
as those given in the Nautical Almanac for 1 840. On this subject the 
Introduction to the Radcliffe Catalogue of Stars, pages 4 and 5, may be 
consulted. 

The Table of Clock Errors and Rates actually adopted will be 
found at page 82 and following pages, which requires no explanation, 
except that, as the rates are deduced by comparison of the clock error 
•corresponding to the mean of the group on any given day with the 
dock errors on the days of observation immediately preceding and 
following, there is given to each result a weight inversely proportional 
to the number of intervening days.

vi Introduction to the Astronomical Observations 

It has been previously stated that the clock was made by Dent. 
Its number is 13 17. 

The ninth column contains the Observed Apparent Right Ascen- 
sions of the objects observed, and is formed by the application of the 
instrumental and clock corrections given in preceding columns to the 
numbers in the fifth column, together with the correction for semi- 
diameter in the case of the Moon. The adopted times of passage of 
Moon's semi-diameter will be found in the foot-notes. They are taken 
from the Nautical Almanac, with a slight correction for difference of 
longitude. 

The tenth column contains the corrections (with the proper signs) 
to Mean Right Ascension for Jan. i, 1858. Those of stars in the 
Nautical Almanac are taken from that work by comparison of the 
Mean and Apparent Right Ascensions for each day required. Those in 
the Catalogue of the British Association are computed from the constants 
therein given, in conjunction with the values of log. A, log. B, log. C, 
and log. D, given in the Nautical Almanac. For other stars, the cor- 
rections have been computed from the formula given at page 363, of 
the Nautical Almanac for 1858, in conjunction with the values of 
log. A, log. B, log. C, and log. D. 

Some notice will be found in the foot-notes, of the relative 
positions of the components of double stars. The ordinary notation 
has been used to mark the quadrant in which the unobserved star 
is situated, with regard to its companion. When these symbols are 
accompanied by figures, those which precede mark the estimated dif- 
ference of N.P.D., and those which follow, the difference of R.A. 
These notices refer to the real positions, not to the positions as they 
appear in an inverting telescope. 

Section II. — List of Stars used in 1858 Jbr obtaining the Clock and 
Azimuthal Errors; Instrumental Errors used in the Reductions; and 
Errors and Rates of the Transit-ClocL — ^Pages 70 to 84. 

These Tables have been previously referred to, and require little ex- 
planation. The Assumed Right Ascensions of the Stars used for Clock Errors 
are deduced from the Radcliffe Observations of former years, and the 
adopted equinox is based frmdamentally upon that used in the Nautical 
Almanac of 1840, which does not differ much from that adopted in the 
Greenwich Catalogues. The Table of Instrtim^ntal Errors will show the 
constancy of the adjustments of the instrument, and the care which 
has been used to determine for every night of observations distinct values 
of the Errors of Level and Azimuth. The Table oi Errors and Rates of

tie Clock gives the mean dock-error for every night, corresponding to 
the mean of the Sidereal times of transit of all stars used for the 
determination of clock errors. 

The columns of " Clock's Loss in 24 Hours'^ and of ^' Adopted 
Daily Losing Bate'', can be very readily verified. 

Section III. — Separate Remits for Mean R.A. of Stars observed 
in the Year 1858. — ^Page 85. 

These results are extracted without alteration from the Section of 
Observations with the Transit Instrument, by the application of the 
Correetions to Mean R,A, given in the loth column to the Observed 
Apparent R.A., given in the 9th column. 

The nomenclature is essentially the same as that used in Section I, 
excepting that if any errors have been detected in the preceding sections 
in naming the stars according to the rules previously explained, they 
are corrected in this section. 

S£cnoK IV. — Observations with the Meridian Circle; and Computations 
of Geocentric N.P.JD. — ^Page 119. 

The Meridian Circle with which the Observations were made was 
constructed by Jones, on essentially the same principles as those em- 
ployed in the Armagh Circle. It is 6 feet in diameter, and carries a 
telescope of the same length, provided with an object-glass of 4 inches 
dear aperture. The magnifying power used in ordinary observations 
is rather higher than 100. The divisions of the circle are on its flat 
side next to the pier, and are read by four micrometer-microscopes 
placed at intervals of 90"* round the circle, at diameters inclined to the 
horizontal line at angles of 45°. They are i6|**» in length, and are 
attached to the flat edge of the cylindricaUy shaped pier, the eye-pieces 
being in the same plane with the back of the pier. An additional 
protection from unequal warmth, whether of the observer's body, or of 
the lamp used for illumination, is provided by a ring of wood carried 
round the circle between the divided band and the interior surface of 
the pier, perforated only under the microscopes, and with small 
portions cut away, to allow the light from the lamp to fall on them. 
This wooden ring is not continued farther than the two lower micro- 
scopes. The four micrometer-microscopes are read for every obser- 
vation. 

A fidler description of the Instrument is given in the first 
volume of the Radcliffe Observations. 

The observations were made by Mr. Quirling.

viii Introduction to the Astronomical Observations 

The Jirst and second columns need no explanation. 

The third, fourthy 9ixA fifth columns give the readings of the Baro- 
meter, and the exterior and interior Thermometers used for the compu- 
tation of the refraction. The Barometer is by Newman, and is used as 
a standard (see Meteorological Observations, page [3]). The Ther- 
mometers have been in use since the year 1840, and were originally 
compared and found to agree with those formerly at the Boyal Society. 
{Radcliffe Observations , Vol. /. p. 19.) 

The sixth column contains the names of the stars or other objects 
observed, the same rules for nomenclature being used as in preceding 
sections. 

The seventh colimin contains the concluded Circle Reading corre-. 
spending to the Mean of Microscopes, corrected for reduction to the 
meridian when necessary in the case of the Moon or of stars near the 
pole. It is the ordinary practice to observe by the Circle Clock (Shelton) 
the time of transit of each object over the centre wire, and to compare 
the Clock with the Transit Clock, for the purpose of attaining the 
deviation of the centre wire from the Meridian, or for obtaining accu- 
rately the Sidereal time at which an observation is made, when the 
star is not bisected at its passage across the central wire. 

In such cases the correction for curvature is applied for all objects 
as deduced from the formula — 

^ „ - ^ Sin« i Hour Angle X Sin 2 N.P.D. 

CoiT°. for curvature = ^ ^ — ;; . 

Sin I 

and, in the case of the Moon, the additional correction for change of 
N.P.D. between the time of observation and the time of meridian 
transit, is applied. 

For computation the preceding formula may be more conveniently 
represented thus : 

Corr». = Number (log = 6*43569) x Sin 1 N.P.D. x <«, 

where t is the interval in seconds of time between the time of observa- 
tion and of meridian transit. 

As a general rule, in reading off the Microscopes, the point of 
intersection of the cross-wires is brought upon the division next below 
the zero (care being taken always to turn the screw of the Micrometer 
in the same direction), unless the zero happens to be within one minute 
of the division above; then that division is used. In other cases, 
when the division above has been employed, mention is made in the 
notes. ' 

The eighth column contains the correction to Circle reading for 
refraction, and the sign of its application will be understood by remem-

bering that increasing Circle Readings correspond to decreasing South 
Zenith Distances^ and by attention to the other elements given at the 
foot of each page. The refractions are calculated from BesseFs Tables 
as given in the Appendix to the Greenwich Observations for 1853, but 
diminished in the proportion of i : 0*9967, in order to make the results 
identical with those of the Tables in Bessel^s Fundamenta AstronondcBy 
as these were found to be more consistent with the Radcliffe observations 
than those of the TabulcR Begiomontana. {See Radcliffe Observations^ 
Vol. Xr, p. 34, &c.) 

The ninth column contains the minute and second finally corrected 
for Runs, Index Correction, and Refraction, and, in the case of the 
Moon, for Parallax and Semi-diameter. 

For runs of the microscopes, the adopted values on 5' will be 
found at the foot of each page, and a general table of them is given 
at page 177, as determined once a week for the mean of the four 
microscopes. The proportional part corresponding to the distance 
from the zeros of the microscopes at which the bisections have been 
made, is applied to each observation. 

The zenith points, corresponding to index corrections, are given 
at the foot of each page, and are determined (or rather the nadir 
points) by observing the coincidence of the horizontal wire with its 
reflected image in a trough of mercury, by means of a Bohnenberger's 
eye-piece, in the usual way. A table of the weekly determinations 
of nadir point will be found at page 177, each being the mean of four 
observations, from which those actually used for particular days are 
interpolated. The values actually used are inserted at the foot of each 
page. 

For the Moon, the horizontal equatorial parallax and the semi- 
diameter are interpolated by second differences for the time of Oxford 
transit from the numbers given in the Nautical Almanac without 
alteration. The parallax applied to the observation is computed from 
the formula — 

Parallax = r x Equ. Hor. Par>. x Sin Distance from Geocentric Zenith, 

where log. r = 9*99910, and the angle of the vertical is assimied to be 

11' 10", as computed from the ellipticity of the earth . As the 

results are given only to one place of decimals, no sensible error is in- 
troduced by substituting the arcs for the sines in the computation of 
the parallax. 

In all interpolations from the Nautical AlmanaCy the Longitude of 
the Observatory has been assumed to be 5™.2i'-6, west of Greenwich;

X hitroduction to the Astronomical Ohservatiom 

this being* the regult of a very careM chronometrieal determination 
made in 184^^ bj the late Rev. Richard Sheepshanks. 

It is stated at the foot of each page^ that the assumed colatitude 
is 38'' 14' 24''' 8. This is essentiallj the same as that determined by 
Mr. Johnson and given in the Introduction to the Observations for 1 854, 

p. XXV. 

Section V. — Table of Nadir Points and of Corrections for Runs of the 
Microscopes of the Meridian Circle, — ^Page 177. 

The observations of the Nadir-pointy and of the Runs of the 
Microscopes of the circle^ are made usually on the Saturday of each 
week. 

During the year 1858^ no micrometer was attached to the tele- 
scope^ and the observations of the reflected image of the fixed horizon- 
tal wire in a trough of mercury were made by bringing it into coinci- 
dence with the direct image^ by the tangent screw of the clamp. The 
operation was repeated usually four times^ the circle being read a&esh 
at each observation^ and care being taken at each alternate observation 
to make the coincidence by turning the tangent screw in the direction 
opposite to that used in the preceding. The reflected and direct images 
of the wire were not brought into contact on opposite sides^ but the 
attempt has always been made to observe the actual position of coinci- 
dence of the images. A correction of +o"'36, has been applied to the 
observed results for the assumed errors of the division of the circle 
which are under the microscopes. 

The observations for runs were made each week for four readings 
of the pointer, at intervals of 90°, namely, for pointer readings, 300°, 
30°, 120°, and aio°. By this process it is plain that the values of the 
runs for only one set of divisions have been obtained, since the same 
divisions are brought successively under the microscopes at each 
change of position. The results therefore are not good representatives 
of the mean error of the runs, as applicable to circle readings made 
in various positions of the circle in the course of observation. 

The tenth colunm gives the Geocentric N.P.D. of Centre of the 
Objects observed. The concluded circle reading, as cleared of all 
instrumental corrections and all corrections depending on the position 
of the observer, can be deduced from the ninth coltmm, reference being 
made to the seventh column for the degrees of circle- reading, and the 
Gteocentric N.P.D. is deduced immediately by subtracting the readings 
thus corrected from 68° 14' 24"' 8, or from the colatitude increased by 
30"*, the latter being approximately the value of the zenith point. The

sign of the subtraction should shew whether the star has been observed 
above or below pole^ but by inadvertence the minus signs have been 
omitted in the cases of stars observed below the pole. 

The eleventh column gives, with its proper sign, the Correction to 
Mean N,P.D. for 1858, Jan, i, and the explanation given for the 
similar corrections to Mean R. A. will suffice for these corrections. 

Section VI. — Separate Results for Mean N.P,D. of Stars observed 
in the Tear 1858. — Page 178. 

These results are deduced without any alteration &om those of 
the Section of Observations with the Meridian Circle^ by application of 
the Corrections to Mean N.P.D.for 1858, Jan. i, given in the eleventh 
column, to the Geocentric N.P.D. of Centre, given in the tenth 
column. 

The same rules for nomenclature are observed as in preceding 
Sections. 

Sesction VII. — Catalogue of Concluded Mean R,A. and Mean N.P.D 
for 1858, Jan. i, ^ Stars observed in the Year 1858; mth the Annual 
Precessions. — ^Page 209 to 254. 

Many of the columns require no explanation, and notice will be 
taken only of those which require it. 

The magnitudes of the stars are the means of those derived from 
observations in the year 1858, as they are given in Sections III and VI. 

The Mean Right Ascensions for 1858, Jan. i, are the means of 
those given for each star in Section III without any alteration. 

The Precessions in R.A., for stars in the Nautical Almanac list, 
are taken from that work, and therefore include Proper Motion. For 
stars included in the British Association Catalogue, the Geometrical 
Precessions there given are set down, due regard being had to secular 
variation in bringing them up to 1858. For other stars, some are 
taken from the Radcliffe Catalogue, the secular variation being applied, 
and the rest have been computed with the same elements, which are 
those of the Tabula Se^iomcntana. 

The same explanation will serve for the Precessions in N.P.D. 

The Mean North Polar Distances for 1858, Jan. i, are tljie means 
of those given for each star in Section VI, with the same corrections 
which have been used in preceding years, as resulting fi^m the discussion 
in the Introduction to the fifteenth Volume of the Radcliffe Observer 
tions, page xviii, &c. 

In combining the observations of stars below the pole with those

observed above the pole, equal weights have been given, as the number 
of instances of such combination is very small, and in each instance 
the number of observations below the pole is small, compared with the 
nimiber above. 

SEcmoN Vni. — Observed Right Ascensions and North Polar Distances of 
the Moon's Centre, compared with the Nautical Almanac. — ^Page 7,^^, 

The Mean Solar Times of Transit of Centre are computed by 
means of the Right Ascension or Sidereal Time, by adding together 
the Mean Solar Time at the transit of the First Point of Aries next 
preceding, and the equivalents in Mean Solar Time for the hour, 
minutes, and seconds of Sidereal Time, allowing 5" 2'. 6 for West 
Longitude. The Observed Right Ascensions are extracted without 
alteration from the Section of Observations with the Transit Instrument ; 
and the Observed North Polar Distances from the Section of Observa- 
tions with the Meridian Circle, corrected for the discordance between 
direct and reflexion observations. The Seconds of N. A. are interpo- 
lated for difference of longitude between Oxford and Greenwich from 
the places given in the Section of Moon Culminating Stars of the Nau- 
tical Almanac. The other columns need no explanation.

INTRODUCTION. 



1 HE Observations were made by Mr. George Green, the Assistant 
charged with all duties relating to the Meteorological department of 
the Observatory, as in former years. Mr. Green takes the general 
management of the Meteoro-Photographic Instruments, prepares the 
Photographic Paper, and makes such Observations with the ordinary 
Meteorological Instruments as are necessary for verifying or correct- 
ing the assumed Zeros of the Photographic Instruments. Mr. Green 
is also charged generally with the reduction of the Observations, but 
the greater portion of the discussions relating to diurnal inequalities 
of Meteorological elements has been performed by myself. 

Ordinary Instrv/ments. 

There has been no change whatever in the Instruments since the 
year 1857, and the account given of them for that year by Mr. John- 
son may be su£Scient. It is desirable however in this place to give a 
more distinct account of all that were in use in 1858, referring to 
former volumes for detailed descriptions and statements. 

The ordinary Meteorological Instruments which were used in 
1858 are the following: 

I. A Barometer by Newman, placed in the N. E. comer of the 
Circle Room, with its cistern at an elevation of q,\ feet above the floor. 
The tube of this Barometer is 0*528 inches in diameter. The Zero of 
the graduated scale is marked by the apex of an inverted ivory cone, 
to which the sur&ce of the mercury in the reservoir is adjusted before 
reading : the Vernier will read to -002 of an inch. The correction for 
capillarity is +0^-003. 

The old Barometer by Bird, used till 1838, is in the old Quadrant 
Boom. 

a. A Dry Bulb Thermometer by Negretti and Zambra, used as the 
standard, N^. 230. 

3. A Wet Buld TAermom^eter by ditto, N®. 230. 

4. A Dry Maximum and a Dry Minimum Thermometer by ditto, 
N*. 1056 and 65a.

[4] Meteorological Observations made in the Year 1858, 

5. A JFet Bulb Maximum and a JFet Bulb Mtnimum 2%ermomeUr, 
by the same makers, N". 1055 and 740. 

All these Instruments were compared by Mr. Glaisher with his 
standard, previously to their being sent to Oxford, and their corrections 
were found to be so small thdt they have been neglected. 

These Thermometers are all placed on one frame, about four feet 
from the groimd, within a Penthouse situated to the North of the 
Observatory, outside the Circle Boom, and at a distance of about six 
feet from the wall< The Penthouse is so constructed of open work as 
to allow a perfectly fi^ passage of air, and at the same time to afford 
a good protection to the Instruments from storms and rain. 

6. A Sky-Eradiation Thermometer, placed on the ground near the 
frame carrying the other Thermometers. 

7. A Solar-Eradiation Tkermometer, with blackened bulb, placed in 
a niche in the South Wall of the West Wing of the Observatory, outside 
the Transit Boom. 

In connexion with the Barometer it may be mentioned, that the 
height of the Cistern above the mean level of the sea has been for some 
years assumed by Mr. Johnson to be 210 feet, by comparison of the 
mean yearly pressures with that given by Kaemtz as the pressure at 
the mean level of the sea, namely, :i9*"*975 for latitudes near the 
Oxford parallel. In 1847, however, Mr. Johnson gives 250 feet as the 
result of this comparison. The height of 210 feet is assumed in the 
reductions of 185^. 

8. Two Rain-gauges; one placed on a slab of stone on a level with 
the groimd on the South side of the Observatory, and at some little 
distance from it ; and the other on the leads above the East Wing of 
the Observatory, at an elevation of 22 feet. The latter communicates 
with a tube leading to a receiving vessel in the North Window of the 
old Quadrant Boom. The rain is poured into a glass graduated vessel 
of one inch diameter, for the purpose of being measured. A little 
evaporation may take place in the gauge on the ground, but, as the 
rain is measured every day, no sensible loss is experienced. 

Photographic Instruments. 

In these there has been no change since the year 1857, except in 
the position of the Anemograph. 

They consist of the following : 

I . A Barograph, placed in a small North Boom between the Transit 
Boom and the Circle Boom, for a description of which, together with 
an account of the method of deducing the value of the scale, &c., &c..

a. A Thermography for observing the temperature of the air. 

3. A Hygrography for observing the temperature of evaporation. 

The Thermograph and Hygrograph are placed side by side on the 
same metal frame, and the case which holds the Camera and the whole 
apparatus is placed very near that containing the other Thermometers, 
at a distance of about 8 feet from the North Wall of the West Wing of 
the Observatory. For a detailed description of these Instruments the 
same Volumes for 1854 and 1855 may be consulted. For these and all 
the other Photographical Instruments gas is employed. 

The comparisons of the Thermog^ph and Hygrograph with the 
Dry and Wet Thermometers are given in the following Table-

4. A Self-regieiering Anemography for shewing continuously the 
velocity and direction of the Wind. A ftdl description of this Instru- 
ment, accompanied by engravings, is given in Vol. xvii. (for 1856) of 
the Badcliffe Observations. It waa originally mounted on a small 
building on the North side of the Observatory, (but at a considerable 
distance &om it,) at a height of 22 feet from the ground, and there 
was placed side by side with it, for comparison, a small portable Ane- 
mometer on Dr. Robinson's principle, designed by Professor C. P. Smyth. 
Near the end of the year 1857 a small building was erected on the top 
of the tower, at an elevation of 1 10 feet above the ground, and, by 
placing there another of Professor Smyth's Instruments, and comparing 
its indications with those of the one below, Mr. Johnson found that, on 
the average, throughout the year 1858, the velocity at the top of the 
tower was greater than that at the lower station, in the proportion of 
2'%6 : I. [Bad, Ohs. vol. xviii. p. [xxiii.] ) The Anemograph was how- 
ever kept in its old position till August 9, when it was taken down, and, 
after some alterations had been made by Mr. Adie of the Strand, it 
was placed in its present position on the top of the tower. From some 
considerations based on the friction of the turning parts of the Instru-

at the Radcliffe Observatory, Oxford. [7] 

ment, Mr. Johnson seems to have been indnced to adopt a graduated 
scale for the redaction of the Photographic indications into velocities^ 
during the time that the Instrument was in its lower position. 

For reading off the Photographic Pictures, the unit of the scale em- 
ployed is i of an English inch, and in one revolution of the third wheel 
employed for giving motion to the index, the space travelled through 
by the index is about 3*3 inches, or 13*2 units of the scale, which is 
nearly the breadth of the Photographic Paper. Mr. Johnson had esti- 
mated that one unit of this scale was, on the average, equivalent to 
about 8 miles of velocity of wind, but instead of using this uniformly 
he employed a Table, of which the following is an abstract : 

01 divisions of scale = i miles.

and this Table was used in the reduction of all the Observations 
made at the lower station, that is, till August 9. After this time, or 
on the removal of the Anemograph to the top of the tower, one division 
of the scale has been assumed to represent 12 miles of velocity. 

Since, however, by the introduction of the two Smyth-Robinson 
Anemometers, (the one placed at the lower station and the other at 
the higher station,) the whole quantity of air in motion for a given 
period can be compared at these two elevations j and since they have 
been separately compared with the Anemograph, first in the lower 
position, and afterwards at the top of the tower, we have excellent 
means for determining whether the scales of velocities corresponding 
to the Registers of the three Instruments have been determined so as to 
give consistent results. The following Table gives the results of this 
comparison :

Hence the ratio of the distances travelled by the cups of the 
Smyth-Robinson Anemometers at the lower and upper stations is 
I : a '25, which is very nearly that given by Mr. Johnson in the 
volume for 1857^ page [xxiii.] 

Again, comparing the sums of distances travelled by the cups of 
Smyth-Bobinson (i) and Anemograph at the lower station for the 
months January to July inclusive, we find them to be, for the former, 
22948 miles, and, for the latter, 23776 miles, or in the ratio of i '036 : i ; 
and, taking the distances travelled by Smyth-Bobinson (2) and Ane- 
mograph, at the upper station, or on the top of the tower, for October, 
November, and December, we find them to be, 21961 miles and 20926, 
or in the ratio of i : 0*953. Hence the ratio is nearly that of equality; 
or the scales of the different Instruments for reduction to miles have 
been well assumed, so as to give velocities on the same scale. 

The method used by Mr. Johnson for determining the unit of the 
scale of velocities for the Anemograph is described in Vol. xvii. p. [xxi.] 
For the smaller Anemometers with Smyth^s modifications, Bobinson's 
theory has been used. These Instruments are of precisely the same 
size and construction. The distance between the centres of the cups 
is exactly 12 inches; and the distance travelled by the cups is

meafiured by a train of wheels^ working in each other^ of which the 
velocity of each is lo times as g^eat as that of the succeeding, the 
circmnference of each being divided into ten equal parts, and marked 
as the dial of a clock. The first wheel is set in motion by an endless 
screw near the lower end of the spindle turned by the cups, and is 
moved through a unit or tenth part of a whole revolution in ten revo* 
lutions of the cups. Hence the space moved through by the cups 
corresponding to a unit of counting of the first wheel is lo x 3^^' 141 59, 
^nd the space travelled by the air is three times this amount, or 
94'*'2477. Hence the number of units of the first wheel which cor- 
respond to a mile of air-motion will be — = 56, very nearly ; 

and, for reduction to miles, the readings of the Instruments have been 
divided by this number. 

The indications of the Smyth-Bobinson Anemometers were read 
daily at 10^ a.m. throughout the year. 

There is also on the tower an Hyetograph, or Self-^regiatering Plu^ 
viometer, (described in Vol. xvii. p. [xviii.]); but its action was found 
to be imperfect, and no continuous records of it exist. 

The last Instrument to be mentioned is an Electrograph, erected 
by Mr. Adie, consisting chiefly of a long copper rod, terminating in a 
sharp spike and pointing upwards above the tower, and giving its 
indications photographically by connexion with a straw Elec^ometer, 
This Instrument has been partially successful, but its records are not 
continuous. 

Daily Results of Meteorological ObservcUions. 

The Tables under this title are intended to give as complete a 
summary of the mean daQy elements of the weather as the size of the 
page will allow. 

The indications of the Barometer and Thermometers, in the 2nd, 
3rd, and 4th columns of the Table, are the means of the 12 daily read- 
ings of the Meteorographic Registers, and represent the means of the 
two-hourly indications, from noon of one day to noon of the next, 
When the Registers are imperfect, the means of the recorded readings 
are reduced to the mean for the day, by the application of the correc- 
tions for the horary changes which are given in Yd. xviii, as deduced 
from three years' observations. 

The highest and lowest temperatures in the shade, in the sun, 
and on grass, were observed with the Self-registering Instruments by 
Negretti and Zambra previously mentioned. The corrections due to

the want of coincidence of their readings with the Standard have been 
applied to their readings. 

The record of rain is that given by the Gauge on the gronnd^ 
which is examined every day at ioI^a.m. 

The amounts of the horizontal motion of the wind are dedtioed 
from the Observations made with the small Anemometer of Professor 
Smyth's constraction on the top of the tower^ according to the scale 
explained at page [7] . The directions of the wind are deduced from 
the twelve daily readings of the Anemograph, and therefore, from the 
commencement of the year till the removal of this Instrument to the 
top of the tower in August, the positions for measuring velocity and 
direction are not identical, but there is no reason to suppose that any 
difference exists in the directions at the two stations. The mean di- 
rections are deduced from the simple arithmetical means of the ordi- 
nates measured on the Photograph, and are afterwards converted into 
the corresponding points of the Compaas. At times when the Anemo- 
graph has &iled, the estimation of direction is the mean of the three 
estimations made by the eye during the day. 

The amount of cloud is estimated as usual fit)m o to 10; o lepv^ 
senting a cloudless sky, and 10 a perfectly overcast sky. In cases 
of a double description, the first applies from noon to midnight : the 
second from midnight to noon. 

The principal elements for determining the general character of 
the weather for each month, together with remarkable meteorie phe- 
nomena, are given at the end of the Daily Results. The phases of the 
Moon are given at the foot of each page. 



Diurnal Inequalities of Mean Monthly Meteorotogieal 

Elements, derived from the Two-hourly Indications 

of the Photographic Instruments, 1858. 

These results are precisely similar to those given in 1857, excepting 
that as, for economy of printing, the actual Meteorographic Blisters 
of Bi-hourly Results are not given in this volume, it was necessary to 
give for the Barometer and the Dry and Wet Thermometers the Mean 
Monthly Indications for every Two Hours. These results form IVkbles 
I, rV, and VII. 

Tables 11, V, VIII, &c., give the constants arising from the solution 
of BessePs Interpolation Equations, for expressing in the usual peri- 
odical formulsB the height of the Barometers, 'Hiermometers, &c., at 
any hour of the day, reckoned from noon, in terms of the mean height

and the hour of the day. In the cAse of twelve values of a fiinction 
observed at equal intervals of time^ the solution is the following : 

If J5^ = J5 + « Sin i^+A) + b Sin {zw-hJB) -f c Sin (sx + C) + &c., 

(where a? is the hour expressed in degrees^) and if o^ i^ ii^ iii^ x, Jii, 

represent the values of the Amotion corresponding to values of w, o^, 

yf, 6cP, 300^, 330^, then we shall find that the application of the 

method of least squares leads to the following determination of the 
values of the constants a,Aji,JB, e, C, &c, : 

B = i-(o-hi+ii+ +x + xi), 

12 ^ 

6a Sin^ = o— vi-f (i— v+xi— vii) Sin6o**-|-(ii— iv+x— viii) Sin 30^, 

6aQ<mA = iii— ix + (ii— x+iv--viii)Sin6o®+(i— xi+v— vii)Sin30% 

6 6Sin^ = o— iii+vi— ix+(i— ii-fv— iv+vii— viii + xi— x)Sin3o°, 

6&Go8^ = (i— iv + ii-v-fvii— x+viii— xi)Sin6o^ 

6e Sin<7 = o— ii-f iv— vi-f viii— x, 

6c Cos C7 3= i— iii + v— vii-l-ix— xi. 

The values of the constants being thus obtained for the baro-» 
graphic^ thermographic^ and hygrog^phic results^ Tables III^ YI^ and 
IX^ are formed by means of them^ by substituting for x in the general 

formula the hourly values, namely, o®, 15°, 30°, 330*^, 345°, and 

thus the hourly values of the diurnal inequalities, or the excesses of 
the hourly vabes above the means for the day, are obtained. 

Table X, giving the Mean^MofUhly ElastioUjf of Vapour for every 
Two Hours of the Bay, is deduced by means of Mr. Glaisher^s Tables 
from the two-hourly values of the temperature of the air and the 
temperature of evaporation, and the mean values of these quantities 
for the year are formulized as in the preceding instances. Table XI, 
giving the Mean^Monihly Val/ues of the Prewwre of Dry Air for every 
Two Hourly is derived from Table X, by subtracting the numbers in 
that Table from the corresponding numbers in Table I. 

Results for the Direction and Velocity of the Wind, 

Table XU is formed in the following mamier : 

Suppose the wind to have blown during the month with a uni- 
form velocity, represented in its statical effects by v, in various direc- 
tions estimated to single points of the Compass or to i i^i, (as they are 
recorded in the Meteorological Register for every two hours for each 
day of every month ;) and let the frequency with which it has blown 
from any one direction making an angle a with the Meridian towards 
the North at any hour, be denoted by n. Then nv may be considered

and to treat the results obtained before August^ and those that follow^ 
quite separately^ especially as a new value of the scale has been used 
after the removal of the Anemograph to the tower. 

The Equations for relative velocities are preferable to those giving 
absolute velocities^ as the value of the scale of velocities seems still 
uncertain. 

Table XV gives the General Changes of the Wind for the year^ 
and it has been formed with great facility from the two-hourly regis- 
ters of direction on the Anemographic sheets^ by noting the times when 
conspicuous changes have occurred from direct to retrograde^ or the 
contrary^ and then finding what have been the whole changes during 
those intervals of time in which the wind has been turning on the 
whole in one direction^ retrograde or direct. The Table gives the 
monthly amounts of changes in both directions^ and^ as usual^ the 
yearly amount of direct motion considerably exceeds that of retrograde 
motion. 

Table XVI, giving the relations of Pressure and Temperature of 
the Air under different Winds, is formed precisely in the same manner 
as in the year 1857, excepting that, for the purpose of economizing 
space, the elements of pressure and temperature have been collected in 
the same Table. Thus, all the elements being taken from the '^ Daily 
Results of Observations,^' they have been grouped so as to reduce the 
whole number of directions to eight, by combining the number of days 
under the principal point with those under the points immediately 
preceding and following, allotting to each a weight proportional to 
the number of observations. Under the North point are included 
therefore the Barometer and Thermometer Readings, corresponding 
to North, N.N. W., and N.N.E., and so on for aU the rest. The 
separate columns of the Table require little explanation, excepting that 
the numbers in Column 6 are taken from the first Table on p. [xxvii.] 
of the volume for 1857, and those in Column 8 from the Table on 
p. [83.] of the same volume, by subtracting the Normal Temperatures 
g^ven in that Table from 48^*6, the normal mean annual temperature. 

Table XVII gives the amount of Bain collected in the two Gauges, 
one placed on the ground South of the Observatory, and the other at 
an elevation of %% feet on the leads of the East Wing of the Observa- 
tory, immediately above the Quadrant Boom. (See p. [4]). The ratio 
of the quantities collected at the two stations, namely i'i8i, agrees 
pretty closely with the result for five years given in the volume for 
1857^ P- [3«^"]> namely 1155. 

Table XVIII, which gives the relations of the Quantities of Bain 
which fell during the year 1858 under different winds, has been formed

The Tables of " Mean Monthly" Results in this section are formed from 
the days in each month in which the two-hourlj records are complete, no 
imperfect days being nsed; while in the preceding section use has been 
made of all the observations recorded. This will account for some slight 
differences in the monthly means.

[36] Inequalities of Meteorological Elements in the Tear 1 858, 

Supposing the general expression for the height of the Barometer 
at the hour — after noon to be represented by the usual formula^ 

B^ = /3-faSin(ar + ^) 4-*Sin(3ar+-B) -f (?Sin(3ar + C) +&c., 

then the following Table gives the values of the constants /3, a, b, c.

The yearly means of the nnmbers under the different hours may be 
represented pretty accurately by the formula 

Eg = o-aSo+o-oii Sin (a? 4-46** 56') -ho-ooa Sin (jia?+ 116** 34'). 

Subtracting the values of the Elasticity of Vapour given above 
from the corresponding numbers in Table I^ we obtain the numbers 
in the following Table.
